Clinical History Flashcards
what are pathognomic symptoms?
symptoms that develop in a specific disease
are pathognomic symptoms common? why or why not?
not common because symptoms overlap
give 2 example of a pathognomic symptom
subcutaneous hemorrhage in a suqare pattern in erysipela in pigs
negri bodies in rabies infected brain tissues
describe the arborizing or algorithm diagnostic method
a flow chart or tree of symptoms to follow to lead you to diagnosis
give an example using the arborizing or algorithm method
symptom: fever, have discharge yes or no? yes leads somewhere, no leads somehwere else. have inflammation yes or no? leads down a different path too
describe the key abnormality diagnostic method
Step 1: general physical examination: for detection of clinically significant abnormalities
Step 2: special examination of suspect systems or organs: physical and laboratory
Step 3: special examination of identified system: exploratory, laparatomy, endoscopy, radiography
Step 4: special examination of lesion: biopsy, response to treatment, examination of fluids
step 5: special examination of specimens: blood, urine, feed, or soil samples by chemical, microbiological, or parasitological means
what does step 1 of the key abnormality method (general physical exam) determine?
abnormality of function present
what does step 2 of the key abnormality method (special examination of suspect systems or organs) determine?
system or organ involved, or body as a whole
what does step 3 of the key abnormality method (special exam of identified system) determine?
location of lesion in system or organ
what does step 4 of the key abnormality method (special exam of lesion) determine?
type of lesion
what does step 5 of the key abnormality method (special exam of specimens) determine?
specific cause of lesion
give an example of systemic or pattern recognition
if observe polyuria and polydipsia WITH weight gain = diabetes
what is the most important skill to have when collecting data before approaching a sick animal?
GOOD COMMUNICATION!!
what are the 2 aspects of good communication as used when collecting data before approaching a sick animal?
set roles: vet to owner, vet to farm etc.
vocabulary used: use the right words, not fancy for fancy sake, but also show you know your shit
list the 5 aspects of animal data that are important to get when obtaining a clinical history
- owner’s information: who to call when things go wrong
- species, type, breed
- animal ID (in herds)
- sex, age, body weight
- production/parameter data
what is important to obtain with sex, age, and body weight information for clinical history for animals in herds?
distribution data for the herd
give 5 types of production parameters/data that would be important to obtain when getting clinical history before approaching a patient (1-3 are for dairy, swine, and chickens respectively)
- milk production, DIM, milk conductivity, milk composition
- litter size, mummified piglets, piglet growth, feed intake
- number of eggs/day
- animals per cage/pen
- neonatal mortality
